My (and my girlfriend's) first attempt at making my own juggling balls

We followed these directions, more or less, along with patterns from this page for a 3", 4-section ball.

I don't know what the weight is, I just filled them with millet until they felt good, which is a little on the loose side for me. We used a sewing machine, the only part sewed by hand is the seam to close up the hole at the very end.

They feel great, and they weren't $10 a pop. Granted, I didn't choose a fancy material, but what I do have works for me. The only disadvantage is that it likes to collect stuff like cat hair, which I have a lot of on my floor.

Regarding sewing your own good quality juggling balls : A web search for 'Barnesy Bags' (often misspelled as 'Barnsey Bags', much to Dave Barnes' annoyance) should turn up some patterns for panel balls.

Dave Barnes has made BBs for the likes of Peter Bone, Ben Beever, and so on, who seem very pleased with the results.

Looking great! If you're looking for a faster and easier way, I can only recommend self made Russian style juggling balls. I guess nothing else is much cheaper or easier to make: http://www.youtube.com/watch?v=eh8yIkrdV9g

I tend to use a lot of layers to help delay that but yes, that'll happen. However its a great cheap way to get people started with their own balls. I'm guessing you're beyond that stage considering the lovely ones you've made but I figured I'd throw in the comment and link for others regardless.
